customisation steps do not work for 20.04

[Peter Jose De Sousa]

Hi,

The guide at https://help.ubuntu.com/community/LiveCDCustomization no longer works to create a custom ISO for Ubuntu desktop on Focal.

The output of the guide on 20.04 has varying results, for example some VMs are able to boot, others are not.

The full steps to reproduce this bug can be found here: https://docs.google.com/document/d/11mVNjaRTPi7tyzfysfet5ih5Xcd_qwOON1aV6mJcu3M/edit.

These steps are known working for 18.04.

Thanks,

Peter

The long term solution for this is probably to get the desktop images built with ubuntu-image so that the hooks feature of u-i can be used for customization.

@William can you expand on that at all?

We need a solution which can be used freely by customers without Canonical's intervention.
